There's a quote for this week about how the book itself is Hunger Games fanfic. I haven't read either, and I'm not familiar with the timing of their publication, so IDK.

My younger daughter has seen Divergent twice, BTW; the first time, in costume. So it works well for twelve-year-old girls. I... have philosophical issues with plots that are tied to special children doing special things, though I'm happy to go along for the ride sometimes. One thing I liked about the bits of Hunger Games that I've read is that Katniss's skills come from her particular situation in life; and that she volunteers, she isn't chosen, and that the circumstance that leads to her volunteering is just dumb chance.
